PUMP MECHANISM.

SPECIFICATION forming part of Letters Patent No. 705,844, dated July 29, 1902.

- Application filed-April 20, 1901.

To @ZZ whom, it may concern:

Be it known that I, EDMUND MASTERS IvENs, residing at New Orleans, inthe parish of Orleans and State of Louisiana,l have invented a new and Improved Pump Mechanism, of which the following is a specification.

My present invention is in the nature of an improved centrifugally-.operating pumping mechanism adapted for' use in deep Wells and for lifting water from bayous and lagoons for irrigating purposes; and it comprehends, generically, a 'casing having a lift-pipe and a discharge-pipe connected thereto, a centrifugally-operating pump-disk held within the casing, and a specially-arranged means for passing the water through the casing in an annular and upwardly-inclined direction.

My present invention inl-its more complete make-up also includes a novel construction of casing cooperating with the disk blades to effect a more uniform and capacious lift action than has been heretofore possible with Aliftpumps having thekordinary arrangement of turbine or centrifugally-operating suctiondisks.

In its more subordinate features my invention consists in certain details of construction and peculiar combination'of parts, all of which will hereinafter be fully explained, and particularly pointed out in the appended claims, reference being had to the accompanying drawings, in which---fV Figure 1 is a vertical section showing my pumping mechanism especially designed for a low-lift pump. Fig. 2 is an enlarged vertical section of the casing and the centrifugallyoperating pumping devices mounted therein. Fig. 3 is a horizontal section'of the casing and the pump-disk, taken practically on the line 3 3 of Fig. 2. Fig. 4 is a plan view ofthe cap portion of the casing. Fig.' 5 isa plan view of the base or receiving portion thereof. Fig. 6 is a plan View of the division bracket-plate that divides the casing into a lower receiving andanupperdischargingcompartment. Fig. 7 is a' sectional elevation of aumodiied coustruction of my invention vparticularly adapted for deep wells. Fig. 8 is a detail view of a modified form of the stops, hereinafter referred to.

Referring to the accompanying drawings,

Serial No. 56,725. (No model.)

in which like numeralsindicate like parts in all the `figures, 1 designates a pump-casing, the peculiar construction of which, in combination with the rotary disk operating therein, forms the essential feature of my present invention. The casing 1 in practice is usually of such diameter as to permit its being slid down into the well-bore, and to facilitate its downward movement and for other reasons hereinafter explained its lower or entrant portion is made tapering, preferably on an angle of forty-tive degrees to the Walls of well-bore, as clearly shown in Fig. 1. The casing 1 consists of three parts-a lower receiving member 12in which the pump-disk operates and which has an inlet 1b, with which the lift-pipe 2 connects, an upper conicalshaped portion 1c for leading the fluid to the otake-pipe 4, and a disk or plate 5, that divides the upper andlower parts of the casing and which also has a bracketed bearing 5fL for the drive-shaft 3. In the preferred construction (best illustrated in Figs. 1 and 2) it will be observed the inlet 1b has a tubular pendent extension 1X, flanged to join with the lift-pipe and formed with a centrally-disposed stepsocket 1C, in which the lower stepped end of the pump-shaftv 3 seats when a solid shaft is used, as shown in Figs. 1 and 2. The socket 1e is in vertical alinement with the bearing 5n in the plate 5.

Upon the inner surfaces of the tapering sides of the part 1fL of the casing is formed a number of inwardly-projecting lugs 8, the inner edges ccof which are disposed in a vertical plane to opposethe outer vertical edges of the pump-disk, presently described and as best shown in Fig. 2. `The front side of the lugsi. e., the side against which the water is forced by the disk blades-inclines from the bottom of the casing forwardly in the direction of the disk rotation, preferably at an angle of forty-live' degrees to the vertical axis of the pump-disk, whereby to produce annularly-inclined ways y (see Fig. 3) to defleet the fluid discharged against the said lugs annularly and upwardly to the dischargeopenings 5e in the division-plate 5, the reason for which will presently appear.

When my improved pumping means is to be used for lifting water from bayous or la- IOO n, te,

the debris that comes up with the water, and` to provide for tting the different lugs 8 8 inV place they may be formed as separate members and bolted to the side walls of the casing, as shown in Fig. 8.

The pump-disk comprises a hub 9, held upon the shaft 3 to turn therewith, from which project in a horizontal plane a number (preferably four) of blades,'the impact-faces of Athe pusher portion 9a of which in transverse elevation snugly fit the spaces between the rim of the inlet, the bottom b of the casing part la, the plate 5, and the straight bore or face of the guide-lugs 8 8, and the said portions 9LL join with the huh 9 by a verticallydisposed shank 9 of reduced area and horizontal webs 9d, the webs 9d being, however, apertured, as at 9e, for a free passage of the fluid therethrough.

The plate 5, before referred to, comprises a body portion having a diameter equal that of the bore in which the disk blades travel, and said plate closes entirelyover the pumpdisk, it being provided with radial extensions 5, that engage the inner vertical annular rim 4d of the cap-plate, as clearly shown in Figs. 1 and 2, said extensions serving to assist in properly positioning the plate, it beingl understood such plate is firmly held down by l the shaft 3, that passes through its central bearing and the fluid-pressure on the top thereof. The pump-blades have their upper and lower edges held to run close against the plate 5 and the bottom of the casing, and to provide for the more eectively lifting the sand and fluid and thoroughly disintegrating the same and force same by centrifugal action against the wall of the casing the impact or pusher surfaces of the blades are vertical, as shown, and the said blades in horizontal plane are curved on a circle eccentric to the axis of the disk, Withtheir outer or impact surfaces x' merging with the circle of the hub, as clearly shown in Fig. 3.

By constructing the pu mp-disk and the casing in the manner described the water-column reaches the pump-disk perpendicular and then passes off toward the annular casing-wall without a turn,'and by reason of the radial inwardly-projecting stops disposed at an angle from the bottom of the casing the iiuid is caused to pass up annularly at an angle of forty-five degrees, more or less, toward the outlets and through the said outlets into the conical cap portion, from whence it passes up into the outlet pipe, which above the ground-line has a discharge-lateral having a back-check valve 10, as shown.

For deep wells and for sinking wells my improved construction of pumping disk and l I casing cany be also advantageously used. For such purpose t-he casing is slightly modified, as shown in Fig. 7, by reference-to which it will be seen the-pendent shaft bearing in the lower casing-section is tubular to permit the shaft 3 to pass down through it to the bottom of the well. Inthis case the hollow drive-shaft 3 also serves as a means for feeding a loosening agent to thebottom of the Well, and upon the lower end said shaft carries a disintegrating means consisting of radial toothed arms 11. In this latter form the lower end of the lift-pipe has a conical receiver to guide the mixed sand, gravel, dsc., up into thesaid lift-pipe. When the disintegrator mechanism is used, a supplemental pipe 2O is mounted within the outlet-pipe that discharges into the top of the casing and has a lateral supply-nozzle 20, that projects through the outlet-pipe and terminates in a nozzle to receive the water-feed hose or pipe. The object in providing the supplemental pipe 2O is to aid in keeping the material separated from clogging Within the casing and pump-disk.

The disintegrating means above referred 4to have been describedin my present application to illustrate the adaptation of my improved mechanism for deep wells, and the said disintegrating means perse form no part of my present invention, as they are fully disclosed in and form 'a part of my -Patent No. 682,939, dated September 17, 1901.
